need help with freeswan!

hello friends,
i have a big problem with freeswan and a w2k roadwarrior.

my net:
192.168.0.55 (Linux Server with Frees/wan)
192.168.0.1 (DSL Router)
192.168.0.81 (Workstation 1)
192.168.0.5 (Workstation 2)

the computers are connected with a wireless lan. but i have a connect to all
machines. if i connected with my client (workstation 1)
over vpn i can only ping the linux server (vpn server). but the machiens
behind this, i.e. 192.168.0.1 is not reachable.

is this a problem because i am in the same subnet? i try a lot, but without
any success!

please help me, i will it to,
best regards,
holger
